Following is mine the current form of code cell in jekyll , and I like to provide a thin border around it.
Here is the portion from my
kramdown: # Use GitHub flavored markdown, including triple backtick fenced code blocks input: GFM auto_ids: true # Jekyll 3 and GitHub Pages now only support rouge for syntax highlighting syntax_highlighter: rouge syntax_highlighter_opts: css_class: 'highlight' sass: style: :expanded # You might prefer to minify using :compressed
and here is the style.scss.
Any suggestion will be highly appreciated.
